1 > IBX Change Log  version (2.3-5 Build 12350) Tue, 25 Aug 2020 16:11:02 +0100
2  
3 < This is rc1 for 2.2.3.
3 > 1.  TIBStringField: when a string value is read from a dataset buffer, if the
4 >    number of UTF8 characters exceeds the string size then string is truncated
5 >    to the maximum string size. This is  usually a problem with fixed width columns
6 >    right padded with white space.
7  
8 < 1. New property for TIBDatabase and TIBXServicesConnection. This is "WireCompression".
9 <   If this property is set to true then the Client will request WireCompression for
10 <   the connection. Note: "WireCompression = true" must be set in the server's
11 <   "firebird.conf". This property is overridden if "WireCompression = true" is set
12 <   in the client "firebird.conf" when wire compression is always requested by the client.
8 > 2.  SQLFiltered and SQLFilterParams added to TIBQuery, TIBTable and TIBDataset.
9 >    If SQLFiltered is set then when a dataset is opened, each line in the
10 >    SQLFilterParams property is assumed to be a SQL condition clause and
11 >    ANDed into the Where clause of the SQL Select statement provided as a
12 >    dataset property. Each such SQL condition thus acts as an additional filter
13 >    on the dataset. (Not yet tested)
14  
15 < IBX Change Log  version                   (2.3-2) Wed, 05 Dec 2018 12:19:23 +0000
15 > 3.  The Filtered property inherited from TDataset is no longer used for SQL (server
16 >    side filters).
17 >
18 > 4. IBLookupComboEditBox: Selection should no longer reset to start of text when
19 >   text matches complete entry.
20 >
21 > 5. TIBDataLink: Detail Dataset params not refreshed unless both master and detail
22 >   dataset are active (avoids risk of access violation if master is inactive)
23 >
24 > 6. TIBEvents: Registered property can now be set at design time even if database not open
25 >
26 > 7. TIBEvents: component now correctly re-initialised after call to UnregisterEvents.
27 >   This should prevent "spillover" of events between sessions.
28 >
29 > 8. TIBCustomDataset: GetNextRecord now called when reseting to first record of a unidirectional dataset.
30 >   This should ensure that the internal buffer is set up correctly and avoids
31 >   a duplicate initial row.
32 >
33 > 9. TIBStringField: DataSize now given as byte size of string less trailing any zero character.
34 >   That is, the DataSize should be the field size * character set width. The
35 >   value returned by DataSize is now the same as the Dataset buffer size reserved
36 >   for the field.
37 >
38 > 10. IBExtract: Tidyup of SQL generation. Avoid unnecessary double quotes.
39 >
40 > 11. TIBCustomDataset: Add checks on buffer sizes when copying data from row to field buffer
41 >    and vice-versa. This may result in an exception being raised (correctly) for
42 >    older programs when using dataset fields added to a form and the database has been
43 >    upgraded. For example, computed fields can change from 32-bit to 64-bit integers.
44 >    In such cases, the field needs to be deleted in the IDE fields editor and then
45 >    added back in.
46 >
47 > 12. IBCustomDataSet: CanInsert, CanEdit, CanDelete and CanRefresh updated to return
48 >    false if query contains white space and not just empty.
49 >
50 > 12. IBCustomDataset: Blob data is now cleared when TDataSet.Cancel is called. This
51 >    should ensure that (e.g.) a TDBMemo is correctly refreshed after a dataset edit
52 >    is cancelled.
53 >
54 > IBX Change Log  version (2.3-4 Build 12041) Fri, 17 Apr 2020 14:00:32 +0100
55 >
56 > 1.  TIBXDataSet and Generators: Generator Names that are not all upper case or
57 >    not SQL Identifiers are now supported.
58 >
59 > 2.  TIBXScript: Set Generator is no longer rejected as unrecognised SQL and is
60 >    passed to the Firebird engine for execution.
61 >
62 > 3.  TIBDataSet: Unidirectional datasets now give an error message if an attempt
63 >    is made to scroll back.
64 >
65 > 4.  New unit: IBMessages.pas. Contains only messages used by IBX and not FBIntf
66 >
67 > 5. TIBLookupComboEditBox: When generating auto-complete SQL, the ListField is now
68 >   only enclosed in double quotes in SQL dialect 3 and when it needs to be.
69 >
70 > 6. TIBLookupComboEditBox: when the list source opens, the ListField name is now
71 >   validated. If no match is found in the list of field names and the database has
72 >   been opened in SQL Dialect 3, then the ListField Name is converted to upper case
73 >   if it then matches a field name. Otherwise, a Listfield not valid exception occurs.
74 >
75 > 7. IBGeneratoreditor.pas: Add missing parenthesis around "IS" statement for compliance
76 >   with fpc 3.2.
77 >
78 > IBX Change Log  version (2.3-3 Build 11512) Fri, 28 Dec 2018 10:04:17 +0000
79 >
80 >
81 > 1. New property for TIBDatabase and TIBXServicesConnection. This is "ConfigOverrides"
82 >   and is used to override the default settings in the client side "firebird.conf" This
83 >   includes "WireCompression" and "WireCrypt". The value of this property is a "TStrings".
84 >   Each line of the string list should be a setting in the same format as "firebird.conf".
85 >   For example "WireCompression = true" in order to request wire compression on the client side.
86 >
87 >   Note: explicit settings in the client side "firebird.conf" appear to take precedence
88 >   over settings given in TIBDatabase and TIBXServicesConnection. Many client side settings
89 >   also require a compatible setting in the server side "firebird.conf". For example
90 >   "WireCompression = true" must also be set in the server's "firebird.conf" for wire
91 >   compression to be used.
92 >
93 >   Whether or not WireCompression or WireCrypt are in use can be checked using the information
94 >   returned with the Client/Server protocol version. See ibx/examples/dbadmin and
95 >   ibx/examples/dbinfo for examples of how to display this information.
96 >
97 > 2. New property for TIBDatabase and TIBXServicesConnection: "WireCompression". This
98 >   is a "convenience" property. If set the "WireCompression=true" is added to the
99 >   ConfigOverrides. If unchecked then this setting is removed.
100 >
101 > 3. TIBExtract: 64-bit integer types are now correctly extracted as "BIGINT" and
102 >   not "INT64".
103 >
104 > 4. New published properties for TIBCSVDataOut, TIBInsertStmtsOut and TIBBlockFormatOut
105 >   These are:
106 >    property TimestampFormat: string;
107 >    property DateFormat: string;
108 >    property TimeFormat: string;
109 >
110 >   Respectively, these provide the date time format templates for SQL types: TIMESTAMP,
111 >   DATETIME and TIME. The format strings use the standard FPC date/time format
112 >   characters (see https://www.freepascal.org/docs-html/rtl/sysutils/formatchars.html).
113 >
114 >   If any of the above properties are set to an empty string, then the locale default
115 >   is used. This uses the ShortDateFormat and the LongTimeFormat. In timestamp, the
116 >   locale default is extended by appending '.zzz' to include milliseconds.
117 >
118 >   TIBCSVDataOut by default sets these properties to the empty string, while the other
119 >   two use: 'yyyy.mm.dd hh:nn:ss.zzz', 'yyyy.mm.dd' and 'hh:nn:ss.zzz' respectively.
120 >
121 > 5. New published property for TIBCSVDataOut:
122 >     property QuoteStrings: boolean (default true)
123 >
124 >   If false then strings are unquoted, otherwise, the QuoteChar property value is
125 >   used to delimit each and every string in the output.
126 >
127 > 6. New published properties for TIBCSVDataOut:
128 >    property FieldSeparator: string;
129 >    property HeaderSeparator: string;
130 >
131 >   Respectively, these provide the separator character(s) used to separate fields
132 >   in data and header rows. Both default to ','.
133 >
134 > 7. New published properties for TIBCSVDataOut and TIBBlockFormatOut:
135 >    TOnFormatTextString = procedure(sender: TObject; var TextString: string) of object;
136 >    property OnFormatTextString;
137 >
138 >   This event handler can be used to process text strings before they are included
139 >   in the output e.g. to replace unprintable characters with alternative strings.
140 >   This only applies to columns with an SQL Type of SQL_VARYING and SQL_TEXT.
141 >
142 > 8. TIBDataSet now raises an exception when ParamByName called with an invalid parameter name.
143 >   Uses "FindParam" if in order to find out if a parameter with a given name exists
144 >   and without raising and exception if it does not.
145 >
146 > 9. TIBQuery now uses IBX SQL Parser instead of the TParams SQL parser in order to ensure
147 >   consistency with SQL queries.
148 >
149 > 10. CaseSensitiveParameterNames property added to TIBSQL, TIBDataSet and TIBQuery.
150 >    When true, SQL statement parameter names are parsed case sensitive. Note for
151 >    TIBDataSet only applies to Select query.
152 >
153 > 11. IBEvents: removing a TIBEvent component from a form should no longer result in
154 >    an IDE exception.
155 >
156 > 12. LocalDBSupport: initial database creation should now work correctly
157 >    when the schema source is an sql file.
158 >
159 > 13. TIBCMLocalDBSupport: new event handler "property OnProgressEvent: TOnProgressEvent"
160 >    when defined, this handler will be called by the internal TIBXScript during
161 >    initial database creation when the schema source is an sql file and may be used
162 >    to provide a visual indication of progress in console mode.
163 >
164 > 14. TCustomIBLocalDBSupport: new public property "InOnCreateDB: boolean". This is set
165 >    to true while a new local database is being created and its schema populated.
166 >    Useful in (e.g.) TIBDatabase.OnAfterConnect handler to suppress actions
167 >    when the database is disconnected/connected during the create DB procedure.
168 >
169 > 15. TIBXScript: any User/password parameters found in a CREATE DATABASE statement
170 >    are now always ignored and replaced by the user name and password provided as
171 >    the login parameters for the TIBDatabase referenced from the TIBXScript. The
172 >    IgnoreCreateDatabase property still applies and the CREATE DATABASE statement is
173 >    completely ignored if this property is true.
174 >
175 > 16. Code tidyup in IBTreeView: Node properties initialisation moved from TIBTreeView.AddNodes
176 >    to TIBTreeView.Added. An OnAddition event handler is no longer needed to initialise
177 >    ImageIndex and SelectImageIndex values on AddNode.
178 >
179 > 17. TIBDatabase.Attachment and TIBXServicesConnection.ServicesIntf properties are now
180 >    read/write. This should enabled (e.g.) multiple instances of TIBDatabase to share
181 >    the same database connection.
182 >
183 > 18. TIBDataSet and TIBQuery now support the TDataSet "Filter" property.
184 >    if provided, this should be an conditional SQL expression suitable for
185 >    including in an SQL Select statement "where" clause. If non-empty and the
186 >    "Filtered" property is true then the SQL expression provided as the value of
187 >    the "Filter" property is "ANDed" with any existing condition statement
188 >    in the SQL statement's "Where" clause.
189 >
190 >    If the "Filter" property is set at run time, the "Filtered" property is true
191 >    and the dataset is already open, then the dataset is closed and re-opened automatically.
192 >
193 >    The "Filter" condition may include IBX style parameters. In which case, their
194 >    value must be set by the dataset's "OnBeforeOpen" event handler.
195 >
196 >    This is a public property for TIBDataSet and TIBQuery query and intended for
197 >    use at run time.
198 >
199 >    Note: The property is a published property of TIBTable. The TIBTable functionality
200 >    is unaffected by this change.
